What’s spectacular about this bike is the expertise. Upon first look, you may be fooled into pondering it is a frequent metropolis bike. Fairly, sure, however modern? Maybe not. That’s till you start to experience it. For one factor, the historically used chain has been changed by a belt drive. That is sensible for decreasing upkeep, and, in my case, dripping oil over the carpets. Moreover, you will discover that there does not seem like any exterior gears – they’re a part of the hub, an Enviolo 380 hub to be exact. 

The Enviolo gear hub isn’t like your conventional hub gears. As a substitute, it makes use of Repeatedly NuVinci Variable Planetary (CVP) expertise, much like that of Repeatedly Variable Transmissions (CVT) featured in some vehicles. The Enviolo hub makes use of balls that may be rotated and incline adjusted, that are positioned between two discs. When the shifter is turned, the linked cable adjusts the balls on the horizontal axis, thus altering the gear ratio. As a consequence of its modern design, the hub provides as much as a 380% ratio vary so you’ll discover a appropriate gear for nearly any utility.

I discovered these stepless gears quite spectacular. The Enviolo grip shift is simple to make use of, even with gloves – which is important for those who anticipate to experience via winter. I by no means discovered I used to be wishing for additional gears with the Enviolo hub; even up comparatively steep hills it carried out properly. Moreover, it’s actually quiet. I’m used to the drone {that a} chain operated drivetrain makes, however this was a revelation.
